Abstract

The invention relates to a universal tube cleaner indicator and belongs to the field of petroleum and gas pipeline mechanical equipment. The universal tube cleaner indicator comprises a trigger component, a transmission component, and an indication component; the upper end of the trigger component is provided with a trigger magnet, and the lower end of the trigger component is provided with a contact which is a universal trigger switch; a first compression spring is sleeved on the trigger magnet; the transmission component comprises a transmission rod and a transmission magnet fixed at the lower end of the transmission rod; the polarities of opposite ends of the transmission magnet and the trigger magnet are the same; and the indication component is connected with the transmission rod. When a tube cleaner or a tube cleaning ball passes through the contact, the contact rises or inclines to drive the trigger magnet of the trigger component to rise; and under the action of magnetic force, the transmission magnet rises to drive the transmission rod to rise. A magnetic force principle is adopted; the universal tube cleaner indicator has the advantages of simple structure, reliable and accurate signal, and convenience in installation, and cannot be worn easily; and the problem of influence on installation directions can be avoided.

Description

technical field

[0001] The invention relates to the field of oil and gas pipeline mechanical equipment, in particular to a universal pig indicator. Background technique

[0002] The pig indicator is an instrument installed on the pipeline or the receiving and receiving ball to detect the passing of the pig or the pig. The existing technology is to open a hole on the pipeline or the receiving and receiving ball, weld the joint, and install the one-way or two-way trigger switch on the joint. When the pig or the pigging ball passes the indicator, the trigger jumps off and the signal is activated. device, this technology has high requirements on the installation direction, and there is a problem of failure. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a universal pipe pig indicator with simple structure and easy installation, which solves the problems of high requirements for installation direction and failure in...
